My son is about 55lbs now, will be 7 in 2 weeks, I am hoping to make it another year with him harnessed but realistically Ill move him to a booster when his sister outgrows her infant seat. Booster seats are all new to me so Im hoping for recommendations so I can start looking for a decent deal!

If I didn't already have two Nautilus that convert to booster and a Graco Turbobooster, I would go for the Britax Parkway for sure. I like the crotch piece that you can secure the seatbelt into to hold it on the lap and prevent submarining.
